Content Pull?

In order to serve your content, a CDN must be able to access it. With content pull, the CDN edge pulls content from an HTTP accessible origin you maintain. This is also referred to as Reverse Proxy. It is the easiest and most common method supported by CDNs. A CDN will either support this or content push (or both)

Content Push?

In order to serve your content, a CDN must be able to access it. With content push, the CDN provides a means (FTP, SCP, rsync, etc.) for you to upload content to a storage repository. This is also referred to as Edge Storage. This method is useful if you cannot (or do not desire to) maintain an HTTP origin server for your content. A CDN will either support this or content pull (or both)

Edge Anycast

Edge Anycast allows a CDN to share a single IP address on multiple edge servers and automatically route users to the server that is topologically closest. When properly configured, Anycast edge routing provides many advantages over DNS including consistent optimal edge server selection, improved reliability due to quicker failover, and elimination of DNS dependencies. However, due to the cost and complexity of properly setting up and maintaining Anycast networks, is is a less common method. Additionally, Anycast routing is often less reliable in less established Internet regions including Asia and South America.

DNS

Domain Name System (DNS) resolves a textual hostname like www.google.com to a numeric address used by computers to communicate. A CDN can use DNS to send requests to closer servers by resolving your CDN hostname (e.g. cdn.mydomain.com) different depending where the request comes from. This is the most common method used because it is easy to setup and administer. However, it can be inaccurate. For example - if the GeoIP database used is out of date or not accurate (a frequent problem with these databases), or if the location of the IP making the DNS query is not the same as the user (DNS queries are from intermediary ISP servers - not users). These issues can result in the user being sent to a slower server. Reliability issues can occur due to DNS query cache when a CDN server is taken offline and users with DNS cache continue to try to connect to it.

EDNS

EDNS is an extension to the Domain Name System that allows intermediary DNS resolvers to include the user's IP address when submitting DNS queries. If supported, the CDN may use this information to determine the user's location (as opposed to that of the DNS resolver) in order to more accurately choose the closest CDN edge server. Because EDNS is new, support is still limited, but the largest public DNS services - Google Public DNS and OpenDNS - now support it.

Proprietary

DNS Anycast

The Domain Name System (DNS) resolves a textual hostname like www.google.com to a unique numeric address required by computers to communicate. Anycast routing allows multiple servers to share a single IP address and automatically route users to the server that is topologically closest. Use of Anycast DNS means resolving your CDN hostname (e.g. cdn.mydomain.com) to an edge server IP address will be generally fast and reliable. Anycast DNS is fairly ubiquitous for CDNs, only minimally improves performance, and should not be confused with the much less common use of edge Anycast which impacts performance more significantly.

SSL Generic Domain?

Does the CDN support SSL content delivery using a generic domain name? This is a common feature allowing you to deliver content over SSL without purchasing an SSL certificate and paying extra for custom SSL

SSL Custom Domain IP?

SSL Custom Domain SNI?

Does the CDN support SNI based SSL content delivery? SNI is a newer SSL hosting method that allows a service to assign multiple SSL certificates to a single IP address. This reduces the associated costs, provisioning complexity and maintenance. However, SNI based SSL is not supported by older browsers

Access Limits?

Log Access?

Does the CDN support access to federated server access logs? These are logs that have been compiled from all CDN edge servers where your content was accessed and stored on a user accessible storage platform

Edge Purging?

Does the CDN allow you to manually remove or replace cached content before it expires? By default content is cached until a designated expiry time (set manually or via origin 'expires' headers). Expiry times for content may vary on different CDN edge servers. Edge purge is useful when you need to quickly remove or replace cached content from all CDN edge servers

SSL SNI Price

Edge Storage Price

If the CDN supports content push/edge storage, and charges a storage fee for its use, this property designates the amount of that fee per gigabyte. If set, the price interval defines the billing frequency for this fee. Alternatively, the storage service property may designate a separate storage service that facilitates edge storage and designates the associated costs (e.g. AWS CloudFront/S3)

Storage Service

Estimated POPs

This property is set if the provider does not disclose the exact locations of the CDN points of presence (also referred to as POPs or edge servers), but has disclosed their numbers. Akamai is a prime example

Provider Managed DNSSEC

Manual generation and management of necessary DNSSEC certificates and digital signatures can be very complex and cumbersome. Some providers simplify this by automating these tasks within their management interface.

Auto Failover?

Auto Scaling?

Does service support autoscaling. For process based platforms this signifies an automatic increase in the number of processes when demand increases. For VM based platforms, this signifies automatic increase in VM resource allocation.

Process Based?

Process based platforms deploy applications using on-demand or dedicated processes (may also be referred to as workers, threads or another name). Each process generally runs in an isolated container that provides memory, (ephemeral) storage and CPU capacity. Multiple processes for the same application may run on different hosts. While process based platforms are often more constrained than VM based platforms (e.g. ephemeral storage, API limitations), they often provide better scalability and fault tolerance

Self Hostable?

Does the provider offer a self hostable option that simulates/duplicates the platform features and functionality, whereby users can deploy applications to other infrastructure (only applicable to process based platforms)?

SSL Generic Domain?

VM Based?

VM based platforms facilitate deployment and management of applications on platform VM instances where they run similar to a VM/virtual host type environment. Generally, libraries and APIs, storage access and other functionality will be similar to self hosting, but the provider will configure and maintain platform VMs. Users typically have limited or no user login access. VM based platforms often do not offer autoscaling and failover capabilities because applications are deployed to a specific VM and if that VM fails, the applications running on it will also fail.

Instance IDs

For block storage services assocated with a compute service - if this storage service is limited to a subset of the compute instance types, these are the instance IDs of those types (one instance ID per line) - regular expressions are ok (e.g. /vmware$/)

Snapshots - Cold?

Snapshots - Hot?

Max IOPs

For block storage services - the maximum number of IOPS supported for the storage service and compute instance - if provisioned IOPs is supported, this is the max number of IOPs that may be provisioned

Max Volumes

Max Volumes - Windows

For block storage services - the maximum number of distinct volumes that can be attached specifically to Windows compute instances (specified only if different for Windows compared to other operating systems)

Price Per Provisioned IOPs

Price Per Snapshot GB

For block storage services with snapshot support - price per gigabyte for volume snapshots (hot or cold) based on the price interval - only specify if different from regular storage pricing and/or from the storage pricing for the referenced Snapshot Storage Service

Setup Fee

Normalized Price

The total hourly price for the compute instance - the fields contains Price normalized to an hourly rate. For term pricing, the setup cost is added to the normalized hourly price for the duration of the term

Linux

Windows

OS License Excluded?

Does pricing exclude the cost of operating system licensing (for commercial operating systems only)? If true, and users intend to use a paid operating system such as Windows or RHEL, additional licensing costs will be required

Backend Process

Frontend Process

Storage

The amount of storage available to each process in GB at this pricing tier - 0 for none, -1 for unlimited or unknown. Process storage is generally ephemeral and coupled to a specific process (only applicable to process based platforms)

Primary/Secondary DNS Support

This section designates the service's support for operating as a DNS Primary/Master or Secondary/Slave. Each column designates support for standard master/slave DNS synchronization methods (when the service is operating in either of these modes) including support for NOTIFY (ability to send or receive), AXFR (full zone transfer), IXFR (incremental zone transfer) and TSIG (Transaction SIGnature).

Primary/Secondary DNS Support

Capability

Primary XFR Support

If this DNS service supports operating as a Primary - this field designates whether it supports NOTIFY (primary to secondary change notification), AXFR (full zone transfer), IXFR (incremental zone transfer) and TSIG (Transaction SIGnature). At a minimum, if supported, this field will designate AXFR (polling) support

Secondary XFR Support

If this DNS service supports operating as a Secondary - this field designates whether it supports NOTIFY (change notifications from primary), AXFR (full zone transfer), IXFR (incremental zone transfer) and TSIG (Transaction SIGnature). At a minimum, if supported, this field will designate AXFR (polling) support

AXFR

Does the service support full zone transfers. When operating as the primary - this is the ability to receive and respond to AXFR requests from secondaries. When operating as a secondary, this is the ability to request AXFR transfers from the primary (due to changes detected from polling or receipt of NOTIFY from the master).

IXFR

Does the service support incremental zone transfers (transfer of only DNS changes since the last update). When operating as the primary - this is the ability to receive and respond to IXFR requests from secondaries. When operating as a secondary, this is the ability to request IXFR transfers from the primary (due to changes detected from polling or receipt of NOTIFY from the master). IXFR transfers are advantageous for large DNS zones that are changed frequently because they minimize transfer and synchronization overhead on both primary and secondaries.

NOTIFY

Does the service support NOTIFY messages when a DNS zone has changed? When operating as the primary - this is the ability to send NOTIFY messages to secondaries. When operating as a secondary, this is the ability to receive them. NOTIFY messages expidite DNS synchronization over standard secondary to master polling and reduce synchronization overhead (by eliminating the need for frequent change polling).
